UNITED STATES PATENT OFFI FREEBORN F. RAYMOND, 2D, OF NEWTON,MASSACHUSETTS, ASSIGNOR TO JAMES w. BROOKS, on PETERSHAM, AND JOHNBROOKS, or CAMBRIDGE,

MASSACHUSETTS, TRUSTEES.

SPECIFICATION forming part of Letters Patent No. 589,396, dated August31, 1897.-

Application filed May 2, 1890- Serial No. 350,309. (No model.)

To all whom, it mag concern.-

Be it known that I, FREEBORN F. RAYMOND,

2d, a citizen of the United States, residing at Newton, in the county ofMiddlesex and State of Massachusetts, have invented a new and usefulImprovement in Heel-Attaching Machines, of which the following is afull, clear,

and exact description, reference being had to the accompanying drawings,forming a part of this specification, in explaining its nature, Theinvention relates toan, attaching-ma, chine having a duplex organizationin which the nailing-heads are independently operated,

but obtain their power from the same prime motor or power shaft.

Referring to the drawings, Figure 1 is a view in vertical centralsection of a machine having the features of my invention. .Fig. 2 is aviewin front elevation thereof. Fig. 3 is a view in side elevationthereof. Fig. 4. is a detail view in section representing crossheads ofsomewhat differentconstruction from those represented in Fig. 1.

A represents the frame of the machine, and

a the bed. Upon the bed are mounted jacks A A the jack A preferablyfacing toward one front of the machine and the jack A toward the otherfront of the machine.

B is the nailing-head used in connection 0 with the jack A, and B thenailing-head used in connection with the jack A Each head has mountedupon ita rotary head or its equivalent for carrying the heel-nailingdevices.

The head B is connected with a crank- 3 5 shaft 1) by means of theconnecting-rods Z) 5 The head B is connected with the crank-shaft b bymeans of the connecting-rods 11 Each crank-shaft has a gear 12 and thesegears are engaged by a pinion b upon the power-shaft U The gears bconstantly rotate upon their respective shafts, and each gear-wheel hasattached to it a section 0 of a clutch. The other member 0 of the clutchis secured to its respective shaft by a key or fast feather 5 to slidethereon, and it is moved into position to engage the member 0 upon thegear by a lever c and springs c and out of engagement with such clutchby a cam 0 upon a gear 0 free to turn upon the power-shaft b andoperated by a gear 0 upon the crank-shaft and a latching-arm 0 Thislatching-arm is connected by means of a rod 0 with a treadle c and isheld in position to engage the cam projection by a suitable spring. 'Oneof the treadles 0 extends to one front of the machine or in position tobe actuated by the operator running the jack A and the other treadle c'to the other front of the machine, or in position tobe actuated by theoperator at that side'of'the machine. It will be seen that from thisconstruction both heads may be simultaneously operated or operated inany order, that the operation of one of the treadles 0 causes anengagement between the gear 011 one crank-shaft and the crankshaft totake place, which reciprocates the head connected with it, while themovement of the other treadle causes a like connection to take placebetween the gear upon the other crank-shaft and that crank-shaft, bywhich the other head is reoiprocated, and that, if desired, bothengagements may be .made at the same time or successively.

I prefer to arrange the mechanism for turning the rotary heads upon theinside of each heador between the two, but this location is notessential. The rotary heads may be moved by cross-heads having centralcavities, as represented in Fig. 1, or by slide crossheads, asrepresented in Fig. 4, in which case each head would be upon the outsideof the cross-head and its various arms are all acoessible to theoperator.

Having thus fully described my invention,

I claim and desire to secure by Letters Patent of the United States- 1 pl. The combination in a heel-attaching ma chine of two nailing-heads, alast or work-support for each head, a common motor-shaft, twoindependent or separate shafts each of which is connected with themotor-shaft by a separate or independent clutch independently-actuatedmechanism connecting each nailing-head with its actuating shaftcomprising connecting-rods and cranks upon the 5 shaft, as and for thepurposes described.

2. The combination of the frame of the machine having two fronts, thejacks A A mounted thereon back to back to face each front of themachine, the cross-heads B B, a [00 10 section or member 0 of a clutchupon each of the shafts Z) I), a spring for forcing each movable memberof the clutch into engagement with the other member, and separatetreadles, latches, and stopping-cams for each clutch, as and for thepurposes described.
